Is there a crate for changing file metadata?

Hello fellow rustaceans! I need to change the metadata of a file for my chat client, but searching online I couldn't find any crate for this. Does there even exist a crate for this or do I have to use crates which wrap around os system calls (like nix)?

What kind of metadata do you need to set? The standard library already supports some: File in std::fs - Rust . If you look at the platform specific std APIs there is even more: PermissionsExt in std::os::unix::fs - Rust.
